Dr. Patricia Bath becoming the first African American female doctor to patent a medical invention. Patricia Bath’s patent was for a method of removing cataract lenses by using a laser device. Bath’s dedication to the treatment and prevention of blindness led to her invention of the Cataract Laserphaco Probe, which was designed to use the power of a laser to quickly and painlessly vaporize cataracts from patients’ eyes, replacing the more common method of using a grinding, drill-like device to remove the afflictions.
With another one of Bath’s inventions she was able to restore sight to people who had been blind for over 30 years. She also holds patents for her invention in Japan, Canada, and Europe.
